Synchronizing audio content to audio and video devices

ABSTRACT

In one general aspect, a method can include receiving, by a computing device, a selection of a group of devices that receive content under control of the computing device, and identifying a first device and a second device included in the group of devices. The computing device and each device included in the group of devices can be connected to a network. The first and second devices can be available to receive content, under the control of the computing device, from a server connected to the network that is remote from the group of devices and the computing device. The method can include providing an indication that the content be provided to the first device by the server and providing an indication that at least a portion of the content be provided to the second device synchronously with the providing of the content to the first device.

TECHNICAL FIELD

This description generally relates to computing devices, audio devices and video devices. The description, in particular, discusses synchronizing audio content and, in some cases, video content from a computing device to one or more audio and/or video devices.

BACKGROUND

A user may have multiple devices in their environment (e.g., a home, an office) that can play video and/or audio content. For example, a television (TV) can play both audio and video content. Speakers can play audio content. The environment of the user may include multiple TVs (a first TV in a family room, a second TV in a kitchen, a third TV in a bedroom). In addition, the environment of the user may include multiple speakers (e.g., a set of speakers between the family room and the kitchen, a set of speakers in a garage). All of these devices can play audio content and, in the case of the TVs, can play video content. In addition, a user may play streaming media (audio and/or video content) on a mobile computing device (e.g., a smartphone, a tablet computer, a laptop computer).

A user can have a variety of devices that can provide and play audio content (and in some cases video content) in a variety of locations throughout their environment. The user, therefore, may find helpful a mechanism that can allow them to select and control how and where they play selected video and/or audio content (e.g., streaming media).

SUMMARY

In one general aspect, a method can include receiving, by a computing device, a selection of a group of devices that receive content under control of the computing device. The computing device and each device included in the group of devices can be connected to a network. The method can include identifying, by the computing device, a first device and a second device included in the group of devices. The first device and the second device can be available to receive content from a server connected to the network. The server can be remote from the group of devices and the computing device. The first device and the second device can be available to receive the content under a control of the computing device. The method can include providing, by the computing device and to the first device, an indication that the content be provided to the first device by the server, and providing, by the computing device and to the second device, an indication that at least a portion of the content be provided to the second device. The at least a portion of the content can be provided by the server synchronously with the providing of the content to the first device.

Example implementations may include one or more of the following features. For instance, the content can be streaming audio content from a cast-enabled application executing on the computing device. The method can further include casting the content to the group of devices. The content can be streaming audio content. The first device can be a display device including a display area and at least one built-in speaker. The method can further include playing the content on the at least one built-in speaker. The content can be streaming audio content. The first device can be a first speaker and the second device can be a second speaker. The method can further include playing the content on the first speaker and the second speaker. The content can be audio content for playing on a speaker included in the computing device. The method can further include mirroring the content to the group of devices. The content can be streaming audio content from a browser-based application executing in an instance of a web browser application. The method can further include casting the content to the group of devices. The content can be streaming media content including audio and video portions. The first device can be a display device including a display area and at least one built-in speaker. The second device can be a speaker. The at least a portion of the content can be the audio portion of the streaming media content. The method can further include playing the content on the first device. The playing can include displaying the video portion of the content in the display area, playing the audio portion of the content on the at least one built-in speaker, and playing the at least a portion of the content on the second device. The content can be streaming media content including audio and video portions. The at least a portion of the content can be the audio portion of the streaming media content. Providing an indication that the content be provided to the first device can include providing an indication that the audio portion of the content be provided to the first device. The method can further include displaying the video portion of the content on a display device included in the computing device and playing the audio portion of the content on the first device. The playing of the audio portion of the content on the first device can be synchronized with the displaying of the video portion of the content on the display device. The method can further include playing of the audio portion of the content on the second device. The playing of the audio portion of the content on the second device can be synchronized with the displaying of the video portion of the content on the display device.

In another general aspect, a non-transitory, machine-readable medium has instructions stored thereon. The instructions, when executed by a processor, can cause a computing device to receive, by the computing device, a selection of a group of devices that receive content under control of the computing device. The computing device and each device included in the group of devices can be connected to a network. The instructions can further cause a computing device to identify, by the computing device, a first device and a second device included in the group of devices. The first device and the second device can be available to receive content from a server connected to the network. The server can be remote from the group of devices and the computing device. The first device and the second device can be available to receive the content under a control of the computing device. The instructions can further cause a computing device to provide, by the computing device and to the first device, an indication that the content be provided to the first device by the server. The instructions can further cause a computing device to provide, by the computing device and to the second device, an indication that at least a portion of the content be provided to the second device. The at least a portion of the content can be provided by the server synchronously with the providing of the content to the first device.

Example implementations may include one or more of the following features. For instance, the content can be streaming audio content from a cast-enabled application executing on the computing device. The instructions, when executed by the processor, can further cause the computing device to cast the content to the group of devices. The content can be streaming audio content. The first device can be a display device including a display area and at least one built-in speaker. The instructions, when executed by the processor, can further cause the computing device to play the content on the at least one built-in speaker. The content can be streaming audio content.

The instructions, when executed by the processor, can further cause the computing device to play the at least a portion of the content on the second device. The content can be streaming media content including audio and video portions. The at least a portion of the content can be the audio portion of the streaming media content. Providing an indication that the content be provided to the first device can include providing an indication that the audio portion of the content be provided to the first device. The instructions, when executed by the processor, can further cause the computing device to display the video portion of the content on a display device included in the computing device, and play the audio portion of the content on the first device. The playing of the audio portion of the content on the first device can be synchronized with the displaying of the video portion of the content on the display device. The instructions, when executed by the processor, can further cause the computing device to play the audio portion of the content on the second device. The playing of the audio portion of the content on the second device can be synchronized with the displaying of the video portion of the content on the display device.

In yet another general aspect, a system can include a network, a computing device connected to the network and configured to execute an application, and a first device external to the computing device and connected to the network. The first device can be included in a group of devices that receive content under control of the computing device. The system can include a second device external to the computing device and connected to the network. The second device can be included in the group of devices that receive content under the control of the computing device. The system can include a server connected to the network and configured to provide content to the first device and the second device under the control of the computing device. The computing device can provide an indication to the first device that the content be provided to the first device by the server. The computing device can provide an indication to the second device that the content be provided to the second device by the server. The application can synchronize the providing of the content to the first device and the second device.

Example implementations may include one or more of the following features. For instance, the application can be a cast-enabled application. The computing device can be further configured to execute a web browser application. The application can be a browser-based application executing in an instance of the web browser application. The content can be streaming media content including audio and video portions. The first device can be a display device including a display area. The second device can be a speaker. The application synchronizing the providing of the content to the first device and the second device can include synchronizing the playing of the audio portion of the content on the speaker with the playing of the video portion of the content in the display area of the display device.

The details of one or more implementations are set forth in the accompanying drawings and the description below. Other features will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

A user can use technology included in a mobile computing device to provide content to a first electronic device and one or more additional electronic devices separate from but within a given range of communication with the mobile computing device. The electronic devices can be televisions (TVs) and/or audio speakers. The mobile computing device can include, but is not limited to, a laptop computer, a mobile phone, or a tablet. The content can be visual and/or audio content (e.g., streaming videos, streaming music, and streaming media). The mobile computing device can communicate with the first electronic device and the one or more additional electronic devices using a wireless communication network. For example, the mobile computing device, the first electronic device and the one or more additional electronic devices can be part of a wireless communication network (e.g., WiFi).

The technology can be electronics included in the mobile computing device that can interface and communicate with electronics included in the electronic devices. The mobile computing device can communicate with the electronic devices using the wireless network. For example, the mobile computing device, the first electronic device, and the one or more additional devices can communicate with one another over the WiFi network. In addition, the technology can include software and applications included on the mobile computing device that can provide (cast) the content to the first electronic device. The mobile device can provide (cast) the content to the first electronic device allowing the first electronic device to play the content while the mobile computing device can control the playing of the content. The control can include pausing, fast forwarding, and rewinding the content. The mobile computing device can control the volume of the audio. The mobile computing device can perform other functions and run other applications while providing (casting) the content to the first electronic device. For example, a user can use the mobile computing device to search the internet, place and receive phone calls, and send SMS messages. In addition, or in the alternative, the mobile computing device can enter a sleep mode or other reduced power mode while the provided (casted) content continues to play on the first electronic device.

A user may want to synchronize all or part of the content provided (casted) to the first electronic device to one or more of the additional electronic devices. By synchronizing the content, a user can move about their environment (e.g., home, office, business) and view and/or listen to the same content in different locations. The user can use their mobile device to perform other functions and run other applications while providing (casting) the synchronized content to the electronic devices.

FIG. 1 is a block diagram of an example system 100 that allows a user, using a computing device, to provide audio (and in some cases video) content to a group of devices. In addition, the computing device can control the providing of the content to the group of devices and can control the playing of the content on each device included in the group of devices.

The example system 100 can include a first display device 114 (e.g., a television (TV)), a second display device 164 (e.g., a television (TV)), and speakers 118 a-b. The first display device 114 can include a display area 150 and built-in speakers 126 a-b. The second display device 164 can include a display area 170 and built-in speakers 166 a-b. Two built-in speakers 126 a-b and 166 a-b are shown in FIG. 1 for first display device 114 and the second display device 164, respectively, however, the first display device 114 and/or the second display device 164 can include less than two built-in speakers (e.g., a single built-in speaker) or more than two built-in speakers (e.g., three or more built-in speakers). In some implementations, the first display device 114 and/or the second display device 164 may interface with one or more external speakers in addition to the built-in speakers 126 a-b and the built-in speakers 166 a-b, respectively. In some implementations, a display device (e.g., the first display device 114 and/or the second display device 164) may not include built-in speakers and, for the playing of audio content, the display device may interface with one or more external speakers.

Though the system 100 includes a first display device 114 and a second display device 164, example systems can include a single (one) display device or more than two display devices (e.g., three or more display devices). Though FIG. 1 shows a speakers 118 a-b, in some implementations, the system 100 can include one speaker or more than two speakers (e.g., three or more speakers).

In some situations, for example, the first display device 114, the second display device 164, and the speakers 118 a-b can be collectively referred to as a group of output devices. Each device included in the group of output devices can be placed in a different location (e.g., a different room in a house, a different office within an office building). For example, the first display device 114 can be in a bedroom, the display device 164 can be in a family room, the speaker 118 a can be in a kitchen, and the speaker 118 b can be in a living room. The bedroom, the family room, the living room and the kitchen are located in a house. Though not necessarily located together, however, as shown in FIG. 1, the first display device 114, the second display device 164, and the speakers 118 a-b are each interfaced to/connected to the network 116.

The example system 100 can include a plurality of computing devices 102 a-c (e.g., a laptop computer, a tablet computer, and a smart phone, respectively). A user can use one of the computing devices 102 a-c to control providing audio and/or video content to the group of output devices. An example computing device 102 c (e.g., a smart phone) can include a computing device system 112. The computing device system 112 can include one or more processors (e.g., a client central processing unit (CPU) 104) and one or more memory devices (e.g., a client memory 106)). The computing device 102 c can execute a client operating system (O/S) 108 and one or more client applications 128 (e.g., a web browser application 110, a natively operating application 146, and a native application 144) that can display a user interface (UI) on a display device 124 included in the computing device 102 c.

The computing device 102 c can include a microphone/speaker 158. Though a single microphone/speaker is shown in FIG. 1, in some implementations, the computing device 102 c can include more than one microphone/speaker (e.g., two or more microphone/speakers, a single microphone/speaker and one or more additional speakers). Though FIG. 1 shows the computing device system 112 as included in the computing device 102 c, a computing device system similar to the computing device system 112 can be included in each of the computing devices 102 a-b, and can perform operations and functions in a manner similar to the computing device system 112.

The system 100 can include a computer system 130 that can include one or more computing devices (e.g., a server 142 a) and one or more computer-readable storage devices (e.g., a database 142 b). The server 142 a can include one or more processors (e.g., a server CPU 132), and one or more memory devices (e.g., a server memory 134). The computing devices 102 a-c can communicate with the computer system 130 (and the computer system 130 can communicate with the computing devices 102 a-c) using a network 116. The server 142 a can execute a server O/S 136.

In some cases, the server 142 a can be a content server and the database 142 b can be a content repository. The server 142 a can execute a content application 138 that can provide content to the computing devices 102 a-c. The content application 138 can provide content to the first display device 114, the second display device 164, and/or the speakers 118 a-b under the initiation, control, and direction of one of the computing devices 102 a-c.

In some implementations, the computing devices 102 a-c can be laptop or desktop computers, smartphones, personal digital assistants, portable media players, tablet computers, or other appropriate computing devices that can communicate, using the network 116, with other computing devices or computer systems. In some implementations, the computing devices 102 a-c can perform client-side operations, as discussed in further detail herein. Implementations and functions of the system 100 described herein with reference to computing device 102 c, may also be applied to computing device 102 b and computing device 102 a and other computing devices not shown in FIG. 1 that may also be included in the system 100. The computing device 102 b includes a display device 122. The computing device 102 a includes a display device 120. The display device 120 and the display device 122 may function in a similar manner as the display device 124. Though not shown in FIG. 1, the computing device 102 a and the computing device 102 b may include one or more speakers that can function in a similar manner as the microphone/speaker 158.

In some implementations, the computer system 130 can represent more than one computing device working together to perform server-side operations. For example, though not shown in FIG. 1, the system 100 can include a computer system that includes multiple servers (computing devices) working together to perform server-side operations. In this example, a single proprietor can provide the multiple servers. In some cases, the one or more of the multiple servers can provide other functionalities for the proprietor. In a non-limiting example, the computer system can also include a search server, a web crawler server, and a marketplace server.

In some implementations, the network 116 can be a public communications network (e.g., the Internet, cellular data network, dialup modems over a telephone network) or a private communications network (e.g., private LAN, leased lines). In some implementations, the computing devices 102 a-c can communicate with the network 116 using one or more high-speed wired and/or wireless communications protocols (e.g., 802.11 variations, WiFi, Bluetooth, Transmission Control Protocol/Internet Protocol (TCP/IP), Ethernet, IEEE 802.3, etc.).

The web browser application 110 can execute, interpret, and/or display a browser-based application. A browser-based application can run inside a tab or instance of the web browser application using a dedicated user interface, and can provide functionality and an experience that is more rich and interactive than a standalone website but that is less cumbersome and monolithic than the native application 144. Examples of browser-based applications can include, but are not limited to, games, photo editors, and video players that can run inside the web browser application 110. The browser-based application can provide a dedicated UI for display on the display device 124.

Browser-based applications can be “hosted applications” or “packaged applications.” Hosted applications may include at least a portion of a web site that itself includes web pages, in addition to some metadata that may be especially pertinent to the browser-based application or to the user of the browser-based application to allow the browser-based application to perform some particular functionality for the user. Packaged applications can be browser-based applications whose code is bundled, so that the user can download all of the content of the browser-based application for execution by the browser. A packaged browser-based application may not need to have network access to perform its functionality for the user, and may be executed successfully by the browser locally on the computing device without access to a network. Packaged browser-based applications have the option of using Extension APIs, allowing packaged applications to change the way the browser behaves or looks.

In some implementations, the computing device 102 c can run, or cause the operating system 108 to execute, the web browser application 110. The web browser application 110 can then provide, in a web browser UI, a plurality of panes or tabs. In a graphical user interface (GUI) used in the computing device 102 c, the web browser UI can be a two-dimensional object arranged on a plane of the GUI known as a desktop. The web browser UI can include other graphical objects (e.g., a menu-bar, toolbars, controls, icons). The web browser UI can display the graphical objects on the display device 124. A user of the computing device 102 c can interact with the graphical objects to provide input to, or otherwise control the operation of, the web browser application 110.

In some implementations, a web browser application (e.g., the web browser application 110) can provide or “cast” a first tab or page of the web browser application to a group of output devices (e.g., the first display device 114, the second display device 164, and the speakers 118 a-b). The group of output devices are external from the computing device (e.g., the computing device 102 c) that is executing the web browser application. In some implementations, the web browser application can provide a user interface for initiating and controlling the casting of the first tab. In addition, for example, a Web Real-Time Communication (WebRTC) application program interface (API) can be used for browser-based real-time communications.

The natively operating application 146 can be an application that is coded using only web technology (defined here as code that can be implemented directly by a web browser application), such as JavaScript, ActionScript, HTML, or CSS. For example, the computing device 102 c can download and install the natively operating application 146 from a marketplace server using a web browser application (e.g., web browser application 110). The natively operating application 146 can operate using a runtime 148. For example, the CPU 104 or by the O/S 108 can execute or run the natively operating application 146 using the runtime 148. Because the natively operating application 146 is coded using web technologies, no compilation step is required.

Native applications (e.g., the native application 144) can include machine executable code and can be executed directly by the O/S 108 of the client device, whereas, a browser-based application may be incapable of execution without the aid of the web browser application 110.

The client applications 128 can present, provide, cast, or capture and mirror content (e.g., streaming media, streaming audio and/or streaming video) to a group of external output devices (e.g., the first display device 114, the second display device 164, and the speakers 118 a-b). In some implementations, the client applications 128 can present, provide, cast, or capture and mirror streaming audio content to the group of output devices. In these implementations, the first display device 114 can play the audio content on the built-in speakers 126 a-b, the second display device 164 can play the audio content on the built-in speakers 166 a-b, and the speakers 118 a-b can play the audio content.

In some implementations, when streaming audio and video content to the group of output devices, the first display device 114 can display the video (image) content in the display area 150 and can play the audio content on the built-in speakers 126 a-b, the second display device 164 can display the video (image) content in the display area 170 and can play the audio content on the built-in speakers 166 a-b, and the speakers 118 a-b can play the audio content.

In some implementations, either the first display device 114 or the second display device 164 can display the video (image) content in the display area 150 and the display area 170, respectively. In these implementations, both the first display device 114 and the second display device 164 can play the audio content on the built-in speakers 126 a-b and 166 a-b, respectively. The speakers 118 a-b can also play the audio content.

In some implementations, the client applications 128 can present, provide, cast, or capture and mirror streaming audio content to the group of output devices while displaying (in a synchronized manner) video (image) content on the display device 124 included in the computing device 102 c. In these implementations, the first display device 114 can play the audio content on the built-in speakers 126 a-b, the second display device 164 can play the audio content on the built-in speakers 166 a-b, and the speakers 118 a-b can play the audio content. In some implementations, the client applications 128 can present, provide, cast, or capture and mirror streaming audio content to a single output device (e.g., the speaker 118 a) while displaying (in a synchronized manner) video (image) content on the display device 124 included in the computing device 102 c. In some implementations, the client applications 128 can present, provide, cast, or capture and mirror streaming video (image) content to a single output device (e.g., the display area 150 of the first display device 114) while playing (in a synchronized manner) audio content on the microphone/speaker 158 included in the computing device 102 c.

A casting application 152 can discover or identify one or more cast-enabled devices that the client applications 128 included in the computing device 102 c can present, provide, cast, or capture and mirror content (e.g., streaming media, streaming audio and/or streaming video). For example, the casting application 152 can identify the first display device 114, the second display device 164, and the speakers 118 a-b as cast-enabled devices. A user can define a group of external output devices that can receive content under the control of a computing device. For example, the casting application 152 can provide a graphical user interface (GUI) for display on the display device 124 of the computing device 102 c that enables a user to select available output devices for placement in a group of output devices. The user can then select the group of output devices for receiving content.

The natively operating application 146 and the native application 144 can present, provide, cast, or capture and mirror streaming media (e.g., audio and/or video(image) content) to the group of external output devices. The client applications 128 can include a UI that can be presented on the display device 124 of the computing device 102 c. A user can interact with the UI and provide inputs and selections for controlling the providing or casting of the streaming media content to the group of external output devices.

In some implementations, the computing device 102 c can display content in a tab or page of a web browser application. The web browser application can provide or “cast” the tab or page to a group of cast-enabled devices (e.g., the first display device 114, the second display device 164, and the speakers 118 a-b). A cast-enabled device can communicate with a network (e.g., the network 116) using a high-speed wireless protocol such as WiFi, Bluetooth, or Bluetooth LE. For example, the web browser application can provide a user interface for initiating and controlling the casting of the tab. The user of the computing device 102 c can provide or “cast” the tab to the group of external output devices by selecting an icon included on the user interface for the web browser application that initiates the casting of the tab. The content can be provided from the server 142 a by the content application 138 to the group of external output devices by way of the network 116 by using a high-speed wireless protocol (e.g., WiFi, Bluetooth, Bluetooth LE). The computing device 102 c communicates with the server 142 a by way of the network 116 by using a high-speed wireless protocol (e.g., WiFi, Bluetooth, Bluetooth LE) to control the content provided to the group of external output devices.

The client applications 128 can be cast-enabled applications that can control the providing of content to cast-enabled devices (e.g., the first display device 114, the second display device 164, and the speakers 118 a-b). For example, a cast-enabled application can provide a user interface for initiating and controlling the casting of the content from the application to the group of external cast-enabled devices. The user of the computing device 102 c can provide or “cast” the content to the group of external output devices by selecting an icon included on the user interface for the cast-enabled application that initiates the casting.

The computing device 102 c can act as a controller for content provided or casted to a group of cast-enabled devices (e.g., the first display device 114, the second display device 164, and the speakers 118 a-b). For example, the natively operating application 146 and the native application 144 can be cast-enabled applications. For example, the content can be a song and a user can touch (contact, tap) icons provided in a user interface of the application to control the playing of the song. For example, the content can be audio content (e.g., streaming audio from an online radio station) and a user can touch (contact, tap) icons provided in a user interface of the application to control the playing of the audio content.

FIG. 2 is a diagram that shows an example user interface 200 for selecting one or more cast-enabled devices for placement in a group of cast-enabled devices. Referring to FIG. 1, a computing device (e.g., the computing device 102 c) can display the user interface 200 on a display device (e.g., the display device 124). The example user interface 200 can be for a casting application (e.g., the casting application 152). The user interface 200 can provide a list of available devices 202 a-d (e.g., one or more cast-enabled devices) that the client applications 128 included in the computing device 102 c can present, provide, cast, or capture and mirror content (e.g., streaming media, streaming audio and/or streaming video).

For example, the casting application 152 can identify the first display device 114 (e.g., Bedroom TV 202 a), the second display device 164 (e.g., Living Room TV 202 c), and the speakers 118 a-b (e.g., Kitchen Speaker 202 b and Basement Speaker 202 d, respectively) as cast-enabled devices. For example, the available device 202 a-d can be devices that are on the same network as the computing device 102 c. A user can select one or more of the available devices 202 a-d using respective device selection buttons 204 a-d. The user can enter a name (e.g., My Group) for the selected group of devices in the group name input box 206. The user can select the create group button 208 to create the group of selected devices.

In some implementations, a device can be included in more than one group of devices. In some implementations, if a device that is a member of a group of devices is no longer available (e.g., the device is off-line), the group can still be discoverable and a computing device can still provide (present, cast, or capture and mirror) content the discoverable or identified devices that remain in the group of devices.

Referring to FIG. 2, in some implementations the example user interface 200 can include an indication of the status (e.g., discovered/identified, off-line) of the available devices 202 a-d when a user is creating a group of devices.

Though the user has created a group of cast-enabled devices, in some cases, a user can choose to have the computing device 102 c present, provide, cast, or capture and mirror content to the group of devices or, alternatively, to one or more individually selected available devices 202 a-d.

FIG. 3 is a diagram of a user interface 300 that shows an example of a pull-down menu 302 that can display a list of available devices 304 a-d (e.g., one or more cast-enabled devices) that a computing device (e.g., the computing device 102 c) can present, provide, cast, or capture and mirror content to using a browser-based application. For example, referring to FIG. 1, the computing device 102 c can display the user interface 300 on the display device 124. The pull-down menu 302 can include one or more available groups of devices (e.g., group 306 (My Group)) that a user may have created (e.g., as described with reference to FIG. 2). The browser-based application can be an application running in a tab 308 of a web browser application (e.g., the web browser application 110 in FIG. 1). A user can select a casting icon 310 in order to display the pull-down menu 302.

For example, a user can be running a browser-based application that displays an image 312 in the tab 308 of a web browser application (e.g., the web browser application 110). The browser-based application may also provide audio content. The user can select an available device from the available devices 304 a-d that the computing device 102 c can present, provide, cast, or capture and mirror information and data (e.g., streaming video and/or audio content) included in the tab 308 to the selected available device. The user can select the group 306 of devices that the computing device 102 c can present, provide, cast, or capture and mirror information and data (e.g., streaming video and/or audio content) included in the tab 308 to each device included in the group 306 of devices. In some implementations, the content provided to each device included in the group of devices can be based on the type of device. For example, speakers can receive audio content. Display devices can receive image (video) content. In some implementations, the content provided to each device included in the group of devices can be based on a selected way of providing content to a device.

FIG. 4 is a diagram of a user interface 400 that shows an example of a pop-up menu 402 that can display a list of available devices 404 a-d (e.g., one or more cast-enabled devices) that a computing device (e.g., the computing device 102 c) can present, provide, cast, or capture and mirror content to using a cast-enabled application.

For example, referring to FIG. 1, the computing device 102 c can display the user interface 400 on the display device 124. The pop-up menu 402 can include one or more available groups of devices (e.g., group 406 (My Group)) that a user may have created (e.g., as described with reference to FIG. 2). The cast-enabled application can be a native application (e.g., the native application 144). The cast-enabled application can be a natively operating application 146. A user can select a casting icon 410 in order to display the pop-up menu 402.

For example, a user can be running a cast-enabled application that displays an image 412. The cast-enabled application may also provide audio content. The image 412 and audio content can be streaming media (e.g., a movie, a video). The user can select an available device from the available devices 404 a-d that the computing device 102 c can present, provide, cast, or capture and mirror information and data (e.g., streaming media, streaming video and/or audio content). The user can select the group 406 of devices that the computing device 102 c can present, provide, cast, or capture and mirror information and data (e.g., streaming video and/or audio content) to each device included in the group 406 of devices. In some implementations, the content provided to each device included in the group of devices can be based on the type of device. For example, speakers can receive audio content. Display devices can receive image (video) content. The content can be synchronized, for example, such that if the user is watching a move, the image content for the movie can be provided to at least one display device included in the group of devices while the audio content can be provided to at least one speaker included in the group of devices. In some implementations, the content provided to each device included in the group of devices can be based on a selected way of providing content to a device.

FIGS. 5A-C are diagrams that show providing (presenting, casting, or capturing and mirroring) of selected content (e.g., music radio) by a computing device (e.g., the computing device 102 c) to an available group of devices (e.g., group 406 (My Group)). As described with reference to FIG. 1, the available group of devices can include the first display device 114, the second display device 164, and the speakers 118 a-b.

FIG. 5A is a diagram that shows an example user interface 500 for a cast-enabled application (e.g., a music radio application 502). A display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the user interface 500. For example, a user can launch the music radio application 502 included on the computing device 102 c.

The user interface 500 includes a cast icon 504. A user can select the cast icon 504 in order to provide (present, cast, or capture and mirror) content from the music radio application 502 to an identified external device or to a group of devices. The user interface includes a current station indication 532 and a set station selection 534. For example, the user can select the set station selection 534 to select a different (change) the current radio station.

FIG. 5B is a diagram that shows an example cast user interface 518 that includes a my group indicator 512, a bedroom indicator 514, and a kitchen indicator 528 included in a devices tab 516 of the cast user interface 518. A display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the cast user interface 518.

In some implementations, a display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the cast user interface 518 in response to a user selecting the cast icon 504. A cast identifier 510 can provide an indication of the content (e.g., music radio) being provided (presented, cast, or captured and mirrored) to an available group of devices 520 (e.g., My Group) as shown in FIG. 5C. As described with reference to FIG. 2, a user can create the group of devices (e.g., My Group) by selecting one or more devices identified as available to the computing device 102 c for providing (presenting, casting, or capturing and mirroring) content.

In some implementations, a user can navigate to a settings interface included on a computing device. The settings interface can include a selection for setting up casting using the computing device and cast-enabled external devices that are near, on the same wired or wireless network, or in communication with the computing device. The cast user interface 518 can include a devices tab 516 (a devices selection). The user can select the devices tab 516 and be provided with the example cast user interface 518. In this example, the cast identifier 510 provides an indication of the content (e.g., music radio) being provided (presented, cast, or captured and mirrored) to a group of devices associated with the name “My Group” (e.g., the available group of devices 520 as shown in FIG. 5C). In some implementations, the cast identifier 510 can allow a user to select, enter, or input an identifier (e.g., a name) for the content they would like to provide (present, cast, or capture and mirror) to the available group of devices 520 as shown in FIG. 5C.

FIG. 5C is a diagram that shows content provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to an available group of devices 520 created by and selected by the user (e.g., My Group). The available group of devices 520 includes two display devices (e.g., the external first display device 114 and the external second display device 164) and two speakers (e.g., speakers 118 a-b). The content includes visual content 564 (e.g., a single grayscale image) that is provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the external first display device 114 for presenting in the display area 150. The content includes visual content 564 (e.g., a single grayscale image) that is provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the external second display device 164 for presenting in the display area 170.

The content includes audio content that is provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the external first display device 114 for playing on the built-in speakers 126 a-b. The audio content is also provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the external second display device 164 for playing on the built-in speakers 166 a-b. The audio content is also provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the speakers 118 a-b.

The example shown in FIGS. 5A-C can be referred to as group audio casting. Group audio casting is the casting of audio content by a computing device executing a cast-enabled application to an available group of cast-enabled devices.

As described with reference to FIGS. 1 and 2, each device included in the available group of devices 520 can be located in different rooms or areas of a current location of a user. For example, the user location can be a house and each of the devices included in the available group of devices 520 can be located in a different room in the house. The external first display device 114 can be a television located in a bedroom, the external second display device 164 can be a television located in a living room, the speaker 118 a can be located in a kitchen, and the speaker 118 b can be located in a basement. Since the content is provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to each of the devices included in the available group of devices 520, a user can move about the house while continuing to listen to and/or view selected content.

In some implementations, for example, the speakers 118 a-b may be located in the same room. In these cases, a computing device can provide (present, cast, or capture and mirror) audio content in stereo to the pair of speakers 118 a-b, effectively providing a portion of the audio content to the speaker 118 a (e.g., a right speaker) and a portion of the audio content to the speaker 118 b (e.g., a left speaker). In some implementations, a speaker (e.g., the speaker 118 a) can be included in and implemented for a surround sound multichannel audio system. In these implementation, a computing device can provide (present, cast, or capture and mirror) audio content in a form compatible with a surround sound multichannel audio system.

Referring to FIG. 4, a user may be viewing and listening to streaming media content (e.g., a movie, a video) that includes video content (e.g., the image 412) and audio content provided by the cast-enabled application on a computing device. For example, referring to FIG. 1, the user can view the video content on a display device 124 included in a computing device 102 c while listening to the audio content as played on the microphone/speaker 158. In some implementations, the user may want to continue to view the video portion of the content on the display device 124 included in the computing device 102 c while having the cast-enabled application provide the audio portion of the content synchronously to each device included in an available group of devices (e.g., group 406 (My Group)). For example, referring to FIG. 5C, the case-enabled application can provide the audio portion of the streaming media content to the available group of devices 520 that includes the built-in speakers 126 a-b included in the first display device 114, the built-in speakers 166 a-b included in the second display device 164, and the speakers 118 a-b.

This operating mode can be referred to as a group audio stripping. Group audio stripping synchronizes the playback of video content on a display device of a computing device of a user with the playing of the audio content on one or more external cast-enabled devices. In some implementations, the user may want to synchronize the playback of video content on a display device of a computing device of a user with the playing of the audio content on a single external cast-enabled device. These implementations can be referred to as audio stripping.

Referring again to FIG. 4, a user may be viewing and listening to streaming media content (e.g., a movie, a video) that includes video content (e.g., the image 412) and audio content provided by the cast-enabled application on a computing device. For example, referring to FIG. 1, the user can view the video content on a display device 124 included in a computing device 102 c while listening to the audio content as played on the microphone/speaker 158. In some implementations, the user may want to continue to listen to the audio portion of the content on the microphone/speaker 158 included in the computing device 102 c while having the cast-enabled application provide the video (image) portion of the content synchronously to a device included in an available group of devices (e.g., group 406 (My Group)). For example, referring to FIG. 5C, the case-enabled application can provide the video portion of the streaming media content to the display area 150 included in the external first display device 114.

This operating mode can be referred to as private listening. Private listening synchronizes the playing of the audio content on a speaker included in a computing device of a user (e.g., the microphone/speaker 158 included in the computing device 102 c) with the playback of video content in a display area of an external cast-enabled computing device the display area 150 included in the external first display device 114).

In some cases, there may be unique challenges when implementing audio stripping and private listening that can be dependent on the computing device that is providing/sending the content in order to maintain synchronization of the audio and video content.

FIGS. 6A-B are diagrams that show providing (presenting, casting, or capturing and mirroring) of selected content (e.g., a music playlist) by a computing device (e.g., the computing device 102 c) to an available group of devices (e.g., group 306 (My Group)). As described with reference to FIG. 1, the available group of devices can include the first display device 114, the second display device 164, and the speakers 118 a-b.

FIG. 6A is a diagram that shows an example user interface 600 for a cast-enabled application (e.g., a music application 602). Referring to FIG. 1, a display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the user interface 600. For example, a user can launch the music application 602 included on the computing device 102 c. The music application 602 can play music (e.g., songs, streaming audio content) included in a playlist (e.g., a running playlist 606, a morning playlist 608) on one or more speakers included on the computing device (e.g., microphone/speaker 158 included in the computing device 102 c).

The user interface 600 includes a cast icon 604. A user can select the cast icon 604 in order to capture and mirror audio content from the music application 602 to an identified external device or to a group of devices.

FIG. 6B is a diagram that shows an example cast user interface 618 that includes a my group indicator 612, a bedroom indicator 614, and a kitchen indicator 628 included in a devices tab 616 of the cast user interface 618. A display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the cast user interface 618.

In some implementations, a display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the cast user interface 618 in response to a user selecting the cast icon 604. A cast identifier 610 can provide an indication of the audio content (e.g., a music playlist) being captured and mirrored from the music application 602 to an available group of devices 520 (e.g., My Group) as shown, for example, in FIG. 5C. A playlist indicator 620 provides an indication of the playlist (e.g., the morning playlist 608) selected by the user for the music application 602 to play on the computing device (e.g., on the microphone/speaker 158 included in the computing device 102 c).

As described with reference to FIG. 2, a user can create the group of devices (e.g., My Group) by selecting one or more devices identified as available to the computing device 102 c for providing (presenting, casting, or capturing and mirroring) content.

In some implementations, a user can navigate to a settings interface included on a computing device. The settings interface can include a selection for setting up casting using the computing device and cast-enabled external devices that are near, on the same wired or wireless network, or in communication with the computing device. The cast user interface 618 can include a devices tab 616 (a devices selection). The user can select the devices tab 616 and be provided with the example cast user interface 618. In this example, the cast identifier 610 provides an indication of the content (e.g., a music playlist) being captured and mirrored from the music application 602 to an available group of devices 520 (e.g., the available group of devices 520 as shown in FIG. 5C). In some implementations, the cast identifier 610 can allow a user to select, enter, or input an identifier (e.g., a name) for the content they would like to provide (present, cast, or capture and mirror) to the available group of devices 520 as shown in FIG. 5C.

Referring to FIG. 5C, the audio content (e.g., a music playlist) being played on the computing device (e.g., on the microphone/speaker 158 included in the computing device 102 c) by the music application 602 can be captured and mirrored by the music application 602 and provided/casted to the available group of devices 520 created by and selected by the user (e.g., My Group). The available group of devices 520 includes two display devices (e.g., the external first display device 114 and the external second display device 164) and two speakers (e.g., speakers 118 a-b). The content includes audio content that is captured and mirrored by the music application 602 executing on the computing device 102 c to the external first display device 114 for playing on the built-in speakers 126 a-b. The audio content is captured and mirrored by the music application 602 executing on the computing device 102 c to the external second display device 164 for playing on the built-in speakers 166 a-b. The audio content is captured and mirrored by the music application 602 executing on the computing device 102 c to the speakers 118 a-b.

The example shown in FIGS. 6A-B can be referred to as group audio mirroring. Group audio mirroring is the capturing and mirroring of audio content being played on computing device by a cast-enabled application executing on the computing device to an available group of cast-enabled devices.

Referring to FIG. 3, a user can be running a browser-based application in a tab (e.g., the tab 308) of a web browser application (e.g., the web browser application 110). The browser-based application may be capable of presenting, providing, casting, or capturing and mirroring audio content (e.g., streaming audio and/or streaming video) included in the tab 308 to a selected available device or to a selected available group of devices. The user can select an available device from the available devices 304 a-d that the computing device 102 c can present, provide, cast, or capture and mirror the audio content included in the tab 308 to the selected available device. The user can select the group 306 of devices that the computing device 102 c can present, provide, cast, or capture and mirror the audio content included in the tab 308 to each device included in the group 306 of devices.

Referring, for example, to FIG. 5C, the audio content of the browser-based application executing in the tab (e.g., the tab 308) of the web browser application (e.g., the web browser application 110) can be presented, provided, casted, or captured and mirrored to the available group of devices 520 created by and selected by the user (e.g., My Group). The available group of devices 520 includes two display devices (e.g., the external first display device 114 and the external second display device 164) and two speakers (e.g., speakers 118 a-b). A computing device (e.g., the computing device 102 c) can provide (present, cast, or capture and mirror) the audio content to the external first display device 114 for playing on the built-in speakers 126 a-b. The computing device (e.g., the computing device 102 c) can provide (present, cast, or capture and mirror) the audio content to the external second display device 164 for playing on the built-in speakers 166 a-b. The computing device (e.g., the computing device 102 c) can provide (present, cast, or capture and mirror) the audio content to the speakers 118 a-b.

A browser-based application presenting, providing, casting, or capturing and mirroring audio content (e.g., streaming audio and/or streaming video) included in a tab of a web browser application to a selected available device or to a selected available group of devices can be referred to as tab audio casting.

FIGS. 7A-F are diagrams that show providing (presenting, casting, or capturing and mirroring) of selected content (e.g., a television (TV) station) by a computing device (e.g., the computing device 102 c) to a selected device (e.g., one or more of the available devices 204 a-d as shown in FIG. 2) or to a selected available group of devices (e.g., My Group as shown in FIG. 2). As described with reference to FIG. 1, the available group of devices can include the first display device 114, the second display device 164, and the speakers 118 a-b.

FIG. 7A is a diagram that shows an example user interface 700 for a cast-enabled application (e.g., a television application 702). A display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the user interface 700. For example, a user can launch the television application 702 included on the computing device 102 c.

The user interface 700 includes a cast icon 704. A user can select the cast icon 704 in order to provide (present, cast, or capture and mirror) content from the television application 702 to an identified external device or to a group of devices. The user interface includes a current station indication 736 and a set station selection 734. For example, the user can select the set station selection 734 to select a different (change) the current television station.

FIG. 7B is a diagram that shows an example cast user interface 718 that includes a my group indicator 712, a bedroom indicator 714, a living room indicator 722, a basement indicator 724, and a kitchen indicator 728 included in a devices tab 716 of the cast user interface 718, where a user has selected to provide content to a group of devices (e.g., My Group). A display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the cast user interface 718.

In some implementations, a display device (e.g., the display device 124) of a computing device (e.g., the computing device 102 c) can display the cast user interface 718 in response to a user selecting the cast icon 704. A cast identifier 710 can provide an indication of the content (e.g., a TV station) being provided (presented, cast, or captured and mirrored) to an available group of devices 720 (e.g., My Group) as shown in FIG. 7C. As described with reference to FIG. 2, a user can create the group of devices (e.g., My Group) by selecting one or more devices identified as available to the computing device 102 c for providing (presenting, casting, or capturing and mirroring) content.

In some implementations, a user can navigate to a settings interface included on a computing device. The settings interface can include a selection for setting up casting using the computing device and cast-enabled external devices that are near, on the same wired or wireless network, or in communication with the computing device. The cast user interface 718 can include a devices tab 716 (a devices selection). The user can select the devices tab 716 and be provided with the example cast user interface 718. In this example, the cast identifier 710 provides an indication of the content (e.g., a television station) being provided (presented, cast, or captured and mirrored) to a group of devices associated with the name “My Group” (e.g., the available group of devices 720 as shown in FIG. 7F). In some implementations, the cast identifier 710 can allow a user to select, enter, or input an identifier (e.g., a name) for the content they would like to provide (present, cast, or capture and mirror) to the available group of devices 720 as shown in FIG. 7F.

FIG. 7C is a diagram that shows an example cast user interface 740 where a user has selected to provide content to a selected single device (e.g., the device associated with the bedroom indicator 714). For example, referring to FIG. 7F, the external first display device 114 can be associated with the bedroom indicator 714. In some implementations, a user may select to provide the content (visual and audio content) first to the external first display device 114 by selecting the bedroom indicator 714 as shown in FIG. 7C. The external first display device 114 can present the visual content 764 in the display area 150 and can play the audio content on the built-in speakers 126 a-b. A user can choose to further select one or more “audio zones” (one or more additional devices) that can play the audio content.

For example, the user can select an add audio zone button 730 in included in the example cast user interface 740. Once selected, as shown in the diagram of FIG. 7D, an example cast user interface 742 can provide selection buttons 732 a-c that can allow a user to select devices associated with the living room indicator 722, the kitchen indicator 728, and the basement indicator 724 as providing an additional audio zone (the selected device can play the audio content). In the example shown in FIG. 7D, a user has selected to provide the audio content to the device associated with the kitchen indicator 728 by selection the button 732 b. Referring to FIG. 7F, the device associated with the kitchen indicator 728 can be the speaker 118 a.

FIG. 7E is a diagram that shows an example cast user interface 744 that includes a notation that the device associated with the kitchen indicator 728 has been selected as an audio zone. The device will receive audio content for playing (e.g., the audio content is provided to the speaker 118 a for playing on the speaker 118 a).

FIG. 7F is a diagram that shows content provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to an available group of devices 720 created by and selected by the user (e.g., My Group). The available group of devices 720 includes two display devices (e.g., the external first display device 114 and the external second display device 164) and two speakers (e.g., speakers 118 a-b). The content includes visual content 764 (e.g., a TV station newscast, streaming video content of a newscast) that is provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the external first display device 114 for presenting in the display area 150. The content includes audio content that is provided (presented, casted, or captured and mirrored) by a computing device (e.g., the computing device 102 c) to the external first display device 114 for playing on the built-in speakers 126 a-b. The content is also provided (presented, casted, or captured and mirrored) by the computing device (e.g., the computing device 102 c) to the external second display device 164 for playing of the audio portion of the content on the built-in speakers 166 a-b. The content is also provided (presented, casted, or captured and mirrored) by the computing device (e.g., the computing device 102 c) to the speakers 118 a-b so that the audio portion of the content can be played on the speakers 118 a-b.

As described, in some cases, a user may select a single device that receives audio and video (image) content and then separately select one or more additional devices that can function as audio zones. The additional device will be provided and will only play the audio content.

The example shown in FIGS. 7A-F can be referred to as audio group with extended video casting. Audio group with extended video casting is the casting of video (image) information to a single device and the casting of the audio content to at least the single device and, additionally, to one or more additional devices. The user, using a user interface, can select each of the additional devices that can play the audio content. Each additional device that plays the audio content can be referred to as an audio zone.

In some implementations, the computing device (e.g., the computing device 102 c) can provide (present, cast, or capture and mirror) the content including visual content 764 (e.g., a TV station newscast, streaming video content of a newscast) and audio content to the external first display device 114 and the external second display device 64. The visual content 764 (e.g., a TV station newscast, streaming video content of a newscast) can be presented in the display area 150 of the external first display device 114 and in the display area 170 of the external second display device 164. The audio content can be played on the built-in speakers 126 a-b of the external first computing device 114 and the built-in speakers 166 a-b of the external second display device 164. These implementations can be referred to as group video casting. Group video casting is the casting of video content by a computing device executing a cast-enabled application to an available group of cast-enabled devices.

In some implementations, a user can control the playback of content by a computing device that is providing (presenting, casting, or capturing and mirroring) the content to external devices, such as external display devices and external speakers. For example, a user con control the volume of the audio content being played by external speakers. The user can control the playback of the content (e.g., pause, rewind, fast forward, next, previous, play, stop, mute) being played by external devices. In some implementations, a user may have a master control that provides control for all devices of a particular type that are included in the available group of devices. For example, a user may have a master volume control for all speakers included in the available group of devices.

FIG. 8 is a flowchart that illustrates a method 800 for a computing device to provide, present, cast, or capture and mirror content to one or more external devices. In some implementations, the systems described herein can implement the method 800. For example, the method 800 can be described referring to FIGS. 1, 2, 3, 4, 5A-C, 6A-B, and 7A-F.

A selection of a group of devices that can receive content under the control of the computing device is received (block 802). For example, referring to FIG. 3, a user can select to cast the content of a tab or instance of a web browser application to an available group of devices (e.g., the group 306 (My Group)) that a user may have created (e.g., as described with reference to FIG. 2). In another example, referring to FIG. 4, a user can select to cast content of a cast-enabled application to an available group of devices (e.g., the group 406 (My Group)) that a user may have created (e.g., as described with reference to FIG. 2).

A first device and a second device included in the group of devices is identified (block 804). The first device and the second device can be available to receive content under the control of the computing device. For example, referring to FIG. 1, the first display device 114 and the speaker 118 a can be included in the group of devices. The computing device (e.g., the computing device 102 c) can identify the first display device 114 and the speaker 118 a to receive content under the control of the computing device 102 c. Provide to the first device an indication that the content be provided to the first device (block 806). Provide to the second device an indication that at least a portion of the content be provided to the second device (block 808). For example, referring to FIG. 5, a user can select a cast icon (e.g., the cast icon 504) in order to provide (present, cast, or capture and mirror) content from an application (e.g., the music radio application 502) to an identified external device or to a group of devices.

Provide the at least a portion of the content to the second device synchronous with the providing of the content to the first device (block 810). For example, referring to FIG. 5, an application (e.g., the music radio application 502) can synchronize the audio content provided to each speaker included in the available group of devices.
